TOBACCO PII'E.

Application tiled August 8, 1927. Serial No. 211,421.

This invention relates to smoking or tobacco pipes, and nioi'eparticularly to pipes adapted to be used in either right-side-up orupsidealown position.

5 The objects of my invention are to provide a` tobacco pine of thecharacter referred to consisting of few simple and inexpensive parts,which in ay be easily assembled or taken apart, for cleaning or renewinga worn or broken portion, together with simple and efficient means forcleaning the pipe and for collecting and discharging or draining liquidor moisture therefrom, and means for producing a cooling effect upon thesmoke in its i5 passage from the bowl to the mouthpiece and preventingthe unpleasant or biting effect of hot smoke on the tongue or the roofof the mouth, or the entrance of nicotin or moisture and saliva into themouth, and also preventing the clogging up of the smoke channel whileproducing perfect combustion and more satisfactory results than areattainable with tobacco pipes as heretofore ordinarily constructed.

The invention will lirst be hereinafter more particularly described,with reference to the accompanying drawings, which are to be taken as apart of this specification, and then pointed out in the claims at theendof the description. i

In said drawings, Fig. 1 is a side elevation of a tobacco pipe embodyingmy invention; the bowl beiner shown in inverted position in full lines.while its upright position is indi cated in dotted lines;

Fig. Q is a longitudinal sectional view of the pipe shown in Fig. 1 inup-side-down position;

Fig. 3 is a longitudinal sectional view illustrating a modification ofthe invention;

Fig. 4 is a detail view of a broken-away portieri of the bowl of thepipe shown in Fig. 3;

Fig. 5 a vertical sectional view of anx. other modification showing thebowl and stein of a pipe having a curved smoke channel;

Fi 6 is a detail plan view of a broken-away endportion of themouth-piece; and

Fig. 7 is a side view of a preferred forni in of spring with a nippleadjustably secured thereto.

Referring to said drawings, in which the same reference letters are usedto denote corresponding parts in different views, the letter A. in Fi land 2, denotes the bowl with ,integral stem c and detachable extensional which terminates in a preferably wide mouthpiece a2 having severalsmoke ducts therein, though other forms may be used. The several artsmentioned are similar to corresponc ing parts of ipes of known constrution `and they are s own associated with co`` operating elementsembodying my invention, winch 1 will now proceed to describe.

As shown, the bowl A is provided with a lining B which may beconstructed of metal, preferably aluminum, and of cylindrical or conicalform. To facilitate cleaning the pipe and to keep the smoke channel andthe inlet thereto at the bottom of thebowl open `and free from cloggingmatter, I insert in the smoke channel a resilient device of tubularform, preferably a spiral or coiledspring C, which extends through thestern a across the bottom of the bowl and has the convolutions thereofwhich are within the smokechanncl in close contact, while theconvolutionswhich are exposed within the bottom of the` bowl areseparated sutiiciently to provide an intersticed construction adapted topermit air and smoke topass freely` therebetween into the inlet end ofthe smoke channel, while preventing the entrance of bits of tobacco ormatter tending to close the same; thereby providing a spiralconstruction within the bowl throu h which air and smoke may enter thesmo e channel,` which is preferably lar er than usual, and alsoproviding a practica 1y tubular body serving as a lining for saidchannel and forming a conduit connecting the bowl with a smoke andliquid receiving chamber D .in the pipe stem, to receive nicotin andsaliva or moisture drawn `into the stern. The spring C extends entirelyacross the bottom of the bowl to the rear wall thereof and may be heldagainst the bottom of the bowl when the pipe is in upside-down positionby the lining B abutting thereagainst at its lower end, as shown in Fig.2. To the outer end of the spring C is secured, by soldering orotherwise, a disk or washer e, the periphery of which is soldered toorotherwise fixed within a sleeve or ferrule E, which connects the outerend of the stem a with the inner end of a mouth-piece `oreirtension aiofthe stem formed integrally with the mouthpiece a2. The disk or washer e,attached to the spring and ferrule, has a hole through the centerthereof arranged in 4alinement with the smoke channel to permit thepassage of smoke therethrough, and has secured thereto co-incfident withsaid hole the larger end of a tubular cone or nozzle G1, which providesa tubular extension of the smoke channel formed by the spring C. Thesleeve or ferlule E spans the space between the stem and month-piece soas to provide a clear space around the cone or tubular tube C1 andprovide a chamber D to receive liquid or lnois ture exuding trom theslnoke channel. This channel, owing to the contacting convolutions ofthe spring and the conical :form ot the nozzle C1 tends to retard theflow of smoke through such channel, and, in connection with the liquidchamber D, produces a cooling ettect upon the smoke before it enters theextension oi the smoke passage provided by the extension uit of the stemol' the mouthpiece secured thereto. The liquid or moisture exuding tromthe smoke cllallnel is collected in the liquid chamber D and may hedischarged from time to time by either disconnecting the stein andterrule or mouth-piece and shaking the moisture out ot the stem olwithout disconnecting said parts, giving the stenl a sidewise thrust soas to eject the moisture through the smoke passage in the mouthpiece.The open end ot the bowl has secured thereto av cap or cover Gr, wllichis preferably hinged to the bowl at the stein side thereof and providedwitll a snap spring g on the opposite side in which there is adepression adapted to snap over a protuberance on the outer side ot' thebowl alld thus prevent the cap or cover from becolning loose anddropping down so as to spill the burning tobacco when the pipe is in theupside-down positioll. The cap G is provided with numerous pertin-ations.for the admission ot air, and within this cap is placed a body ofreticular material such as Vwire netting, 0r the like, ot circular 0rother tol-m adapted to contorni to the sllape ot the cap and having onthe circumferential edge thereof a cylindri Ial tlallge, whereby itproperly spaced 4trom the ill/lpert'orate end-portion of the cap whichterms the bottoni of the bowl when the pipe is in up-side-down position,tllus providing a false bottom for the bowl when in the latter positionand a support therefor by which it is sustained above the in'lpertoratebottoln so as to provide all air chamber below the bowl when inup-side-down position and above the bowl wllen the pipe in its normalupright position. In either position the operation o't the pipe is verynlucll like that ot a stove, the wire netting or retieular materialacting the same as a grate in a stove, and thus a goed draft is insured,similar to the draft of a chimney. `When the spring C is inserted in thestem a the sleeve or errule E, wllich is secured to the outer end of thespring, is forced over the end of the stein while the outer end of thesleeve tits tightly over the inner end of the extension a? ot the steinor the mouth-piece so as in etl'ect to unite the two parts as one, thusadapting the same to servi as a handle tor removing the mouthpiece andwithdrawing the spring when it is desired to clean out the bowl andsmoke chaunel. I thus provide a iirln airltight connec tion between theterrule and extension oit the pipe stein while at the salue time the twoparts are adapted to he Yforcibly disconnected.

In the form shown in Figs. 3 and il ot the drawings, instead oit' ahinged cap or cover, the cap has its cylindrical body portion extendedso as to overlap the howl to which it is secured by means ot a bayonetjoint connection, as shown at I ill Fig. 4; otlnfrwise the constructionot the cap is substantially identical with the cap previously descrihed.Furthermore, in this lnoditicatioll, the exit end or terlninal C ot thesnfloke channel formed by the spring C is oi tubular torni instead o'tIthe conical torni shown in Fig. Q; otherwise the Lfollstruction sllownin Figs. El 85 and 4 is substantially identical with the constructionshown in Figs. l and Pleterahly the outer end ot the mouth-piece islattened sntlieiently to provide small duets on opi-insite sides of anintermediate duct ot larger size forming a continuation of the smokechannel through the stem, so that smoke is drawn ill larger volumethrough the intermediate duct and a part caused to pass through the sideducts, which are very small ill proportion to the size oit theintermediate duct, so that the smoke issues from the lnouth-piece in adivided stream instead of being concentrated and caused to issue throughone large duct.

In the lnoditication shown ill Fig. 5 ot the drawings, the pipe howl A2is formed integrally with a curved stein o* having a smoke channel whichis curved throughout its length, and in which is inserted a spring ofthesame construction as that described with reference to Fig. 2 ot thedrawings; the resiliency ot the spring or clplivalent device, such as atube torlned ot' wire netting or ther retieular material., permittingthe'insertion thereof in a curved smoke channel.

Fig. 'T ot' the drawings illustrates a spring` such as shown in Figs. 2.3 and 5. having adjustahly attached thereto, a tthe delivery end of thesmoke challnel` a nozzle or nipple C ol elongated tubular torni so as toprovide at one side ot the disk or washer e, a delivery or dischargeend-portion c alld on the other side a shank portion el, the latterhaving iormed thereon or secured thereto studs or pins c', which areadapted to enter between adjacent convolulions or coils ot' the spring,inv one end of which the shank portion of the, tube inserted. so tha` tby rotz'lting the nipple while the spring held stationary, or viceversa, the studs or pills will be caused to move spirally following thecoil ot the spring while the nipple moves in the direction ot the axisot the spring. either t'or ward or back, according to the direction otrotation, thereby adjusting the spring so that it may extend a 13e fit)greater or less distance into and across the bottom of the bowl as maybe found desirable in practical use. In this instance the delivery endof the nipple or nozzle has secured thereto, by solderinglr orotherwise, a detleetor or baille plate c3, against which the smokeimpinges as it passes out of the smoke channel into the liquid chamberI); said baille plate having on opposite sides thereof rearwardlyextending flaps or flanges c* which are soldered or otherwise secured tothe tube so as to leave a .narrow space between the discharge end ol thenozzle and the baille plate.

As the smoke contacts with the baille plate it is deflected or turnedback into the liquid chamber wherein it is condensed and cooled, therebyproducing a dry cool smoke; the moisture aud nicotin being separated bycontact with the batlle plate and caused to drip or drop down into thebottom of said liquid chamber.

In the preferred form of my invention I use the ni pple of elongatedtubular form having the dellector or baille plate on its outer ordelivery end, while its inner end is adjust-- ably secured to the outerend of the coiled spring, but I do not desire to be limited to theparticular form described, as other forms may be employed, and obviouslythe baille plate may be attached to nipples of the form shown in Figs. land Q, with or without the adjustable connection with the spring.
